useful Improvement in Bridges, of which the following is a specification.

My present invention relates to bridges, and more particularly to simple and ehe@- -tive means for protecting and prolonging the life of the cap sills and sleepers, adaptable to the various types of bridges, includ ing'railivay bridges and trestles, dinar-y bridges. l

ln the accompanying dravvings which and the orillustrate the means l employ to this end,

Figure L. is a plan view ot' a portion oi' a bridge, iroin which the transverse flooring strips have beenV partly removed, and illustrating one of the cap sill protecting shields partly broken away, and Fig. :lis a transl verse vert-ical section taken "therethrough substantially on the lineZ-Q of Fig. l'.

Peferring now to these figures, the cap sills are indicatet bye and may be supported in any suitable manner by uprights, piers, piles and the like B, the under struc;- ture et' the brit ge being unimportant in so far as the resent invention is concerned..

Along the oepV sills A. which are arranged transversely usual, are extended the lon gitudinal sleepers C, the ends of which are as usual lapped above certain of the cap sills A as indicated in dotted lines in Fig. l,

ln accordance vwith my invention, l pro# vide protecting shields which entend longitudinally and transversely above the sleep.

ers C, to cover and protect the sain-e and the cap sills, these shields being in the form of transversely curved strips of sheet metal and the longitudinal shields D being eX- tended along and directly upon the upper edges of the sleepers with their meeting ends above certain ot the cap sills and y above the lapped ends of the sltepe and the transverse shields` E beingr disposed upon the shields D, to cover the cap sills A and Certainvi'ii1 these transverse shields being therefore utilized to Cover the lapped ends of the longitudinal shields, before mentioned.

^ lt will be noted that the shields D and E being in the forni described and being of substantially Agreater width than the sleepers and cap sills above which theyy extend,

will edectually protect the cap sills 'and sleepers from Water dripping through the cracks bet-Ween strips l". lt will be noted'that these ilooring-strips are placed 'and held in position by fastening members Which extend there through and through the protecting shields into-the sleepers. Thus in order to properly Vleep up tliebridge, it would only be necessary from time -to ltime to replace the looring in inuoh'as by the use ot shields such as proposed',l the usual life of the cap sills and A'sleepers will be greatlylprolonged.

(ln thefdrawing l' have shown flooring strips-as used npc-n a pedestrian bridge, but itfis jto'be"understood thatA the shields are equally adapted to railroad'bridges in which suitably spaced cross ties are substituted in 'l claiiril. .ln abridge lieu 'of the llooring strips l?.
